Archiving system states by persistent objects

The paper describes one specific aspect of the software component construction in the life cycles of computer based systems. The construction is located following the requirements analysis, conception and design. Systems are designed as within the ECBS process so called services which consist of a set of objects working together, keeping the states of the system. To ensure an efficient and rapid construction of systems an easy to use mechanism to store and retrieve objects together with their relations is necessary. This demands an embedded method of keeping objects in a database-the persistence. The described mechanism is implemented using C++ and verified in some projects. A man machine service is used as an example to show the application of this approach
